There is this girl I have been running into a couple of times now after school. She is always with the same group of 4 girls, and she keeps jumping on my back and taking my hand, sorta cudling up to me, and I'm not sure how to react, I don't know this girl at all, she says that we go to the same school but I've never seen her there. She's pretty hot though and I think she's kinda funny, has a lot of energy. Should I go for it? Or is she just using me to have something to laugh about?
